Question about Brother IntelliFAX 4100 Laser Fax
Please help me. Our business fax says receiving sleep, but none of the faxes are coming through. I cannot get it off of sleep mode and people are calling saying it is busy. I don't want to unplug it and risk losing faxes in memory that need to be printed. How do I get the fax out of sleep mode and back to printing?
The sleep mode is only a power save mode. You may not have the machine in the correct fax receive mode. If the machine is on a line by itself it needs to be set to fax only, if line is shared with a telephone it needs to be in fax/telephone, if you share the machine with an answering machine it needs to be in TAD mode, and so forth. Each time you press the MODE key it will change the receive mode. Most people hit this key by mistake and change the MODE and the unit will not pick up calls. Press the MODE key until you are in the correct mode. To make sure the machine will print, press reports and then the 1, this will print a help list. If the help list prints you know that the machine works. Then check to make sure the machine is in the correct fax receive mode.

I just fixed this identical problem: Incoming calls would not wake the fax machine out of sleep mode. The ringer would not ring when a call was incoming, but if I picked up the handset, the call was there. I had a normal dialtone and was able to place outgoing calls. This problem was intermittent -- it seemed to be affected by weather, humidity, outside temperature, etc. I had to get Qwest out to our site to check the phone line itself. We discovered that the ring generator (telco equipment) on the line was bad. U.S. phone lines operate on a normal line voltage of 48V. When a call comes in, the ring generator circuit generates a pulse of approximately 40V above the normal line voltage, and that's what causes the ringer on the receiving equipment to activate. The ring generator on our fax line was only generating a pulse of less than 10 volts above the normal line voltage, which was not enough to be detected as a ring signal. When the repairman switched the line over to a different circuit with a different ring generator at the telco box outside our facility, the fax machine immediately began working properly and has not been a problem since. I recommend that you have the phone company use a voltmeter to test the ring generator voltage on your line. If it's faulty, they should replace it at no charge to you as it's telco equipment, not Customer Premise Equipment (CPE). Hope this helps!

Try changing the sleep mode settings. Sometimes it's set too long or too short. You can try the perimeter reset as well. The instructions I have for that is as follows:
hit the menu button and numbers *2864 (star before the four numbers)
then hit 91(set) wait a few seconds for the maintenance screen to return
then hit 99(set) when it beeps saying completed that could fix your problem.
Hope this helps.

Is tel line going into correct socket of fax? (Line not Ext.)
Is Fax set to auto answer or manual?
If you pick up line or press speaker button can you hear other fax sending if so press start and hang up you should receive fax, and you have just proven that machine is in manual receive mode!
I think you will find it will wake from sleep automaticly if setup correctly.
